Can column generation be used for generating explanations in ML?

Generating explainable predictions using column generation

ONGOING

This project is concerned with producing interpretable predictions for a multiclass classification problem.

There has been some research using column generation to perform binary classification to generate Boolean decision rules in Disjunctive Normal Form as explanations. We extend this binary classification model to a multiclass classification task by following the classical one-vs-rest approach. One of the major challenges in the project is to assign weights (which also needs to be interpretable) when more than one class is tested positive in the one-vs-rest framework.
